AUTOMATIC ori. FEED.

Application led January 13, 1921. Serial No. 436,915.

To all whom t may concern:

Be it known that I, LEO J.' HINDLE, a citizen of the United States, residinfr at Lowell, in the county of Middlesex and mmonwealth of Massachusetts, have invented a certain new and useful Improvement in Automatic Oil Feeds, of which the following is a specication.

This invention relates to automatic oil feeds particularly for gasolene engines for automobiles.

The objects of this invention are princi- -pally to diminish the production of carbon in the engine,to keep just the proper amount of oil in the engine, too little oil causingthe bearings to be burned and worn out, andtoo much oil flooding the engine causing an eX- cess of carbon and the. spark-plug or plugs, according as there are one or more cylinders in the engine.

By keeping thespark-plugs free from oil, there is a saving of gasolene or other liquid fuel.

This invention enables the driver to know without leaving his seat, just how much oil he has. Said invention enables the driver to maintain the oil at the yproper level in the crank-case.

rlhe invention by lessening destruction of bearings and spark-plugs lengthens the life of the engine and saves the time lost by disuse and the cost of repairs.

In the accompanying drawing, Fig. l is a vertical cent-ral section of the invention applied to the vdash-board of an automobile; Fig. 2, a side elevation of the hood or front part of an automobile and of a part of the frame, the crank-case and feed-tank; and means for attaching the latter to the frame, the said means and the cover of said tank i being partly in section; Fig. 3, a vertical transverse section of the crank case and feed reservoir, but, omitting the mechanical contents thereof.

The dash-board A, hood B and crank-case C, are of any usual construction.

The oil-reservoir D is of convenient shape to be attached to the dash-board by any usual means, as by the gage-elbows E which are provided with shoulders e e and threaded ends which screw into the side of preventing operation of` A of which loosely surrounds the reservoir, and hold it firmly a ainstthe dash-board; A glass gage-tube between the elbows in communication with the reservoir by means of packing nuts e2 e2 in an obvious manner, and enables thedriver to know the exact height of oil in the reservoir.

The reservoir below the lower elbow E* contains a screen d to prevent any solid impurities from passing from the tank. The lower part all of the reservoir is funnelshaped and connected by the pipe d2 to the feed-tank F. 1

The feed-tank is provided with a float g which controls a valve G which determines the depth of oil in said tank. This valve is represented as. comprising a shell or case g having an inlet g1, a plug g2 in alinement with said inlet g1 and longitudinally and horizontally movable by means of a lever g3 fulcrumed on an arm g4 of said shell, `to open or close said valve. f

The lower end of the lever connected to a' bent rod g the `upper'end thescrewthreaded stem g5 of the float g and is adjustable on said stem by nuts said stem above and below the upper end of said rod. The lower end portion of said rod g extends for some distance on the other side of the lever g8 from said float and is screw threaded at g to engage a weight 91 to counter-balance partially the weight of said float and to vary the downward pressure thereof.

The tank F is provided with a cover f* secured thereto as by bolts f5 the joint between the cover and the body of the tank being rendered air-tight by a suitable interposed gasket f3.

The tank is connected to the crank-case by a pipe f1 in an obvious manner as shown in Fig. 3 and is secured by straps f6 to the underside of the frame A1.

Both the reservoir D and tank F are provided in the top with" dust-proof air-passages 13 f2.

g? g8 which turn on.

g3. is rigidly It will bev seen that the course of the oil from the reservoir to the tank is downward practically throughout and that the Weight of the oil in the reservoir and immediately i below the reservoir will force the oil con- 'stantly towards the tank.

I claim as my invention: n The combination of a. crank' case, a main 5 reservoir, an auxiliary reservoir at a lower level, a pipe leading to the auxiliary reservoir, a horizontally moving valve closing the opening to said pipe, a float, a lever control mechanism connecting said horizontally movingvalve with the oat, one' of said 10 levers being bent and provided at one end with a counterweight and at the other end vvith a. vertical screw adjustment y'for thel oat.
